Apparently, LCD's do retain a prolonged image but it's not permenent.
On the Apple site (
http://docs.info.apple.com/article.html?artnum=88343) it says that the "burned in" image can be removed by displaying a totally white screen for the length of time that the "burned" image was displayed for.
This concept should work for LCD TV's as well, in theory.
If a White JPEG was put on a CD a displayed on the LCD, it should cure the problem.
What do you think?
I've been reading about certain DVD players that can zoom in and out of the picture pixel by pixel. So i could simply zoom in to overscaned DVD's and in future, not bother with overscan at all.
Sorry to ask and then research it but i thought this would be useful to other people as well.
